Green stands for calm extraction and clean tea character; yellow brings energy and recognition. E-REN doesn't need visual noise to be memorable. Good tea doesn't need to shout; time does the talking.

Clear bottles, white caps and the green-yellow diagonal label define the E-REN packaging language: clean, bright, and recognizable at a glance.
The first E-REN store opens in November 2026 at No. 10, Sec. 1, Bei'an Rd., North District, Tainan City: a bright green-and-yellow street corner built for easy takeaway and bottled tea on the go. Follow us on LINE for the exact opening date.
